Demi Lovato and her ‘lesbian lover’: Singer blows kisses with on-screen girlfriend Naya Rivera in behind-the-scenes pic on Glee set

It was only days ago that Naya Rivera revealed that the 21-year-old pop star would appear as her lesbian lover on the popular Fox TV series, and Thursday marked her very first day of filming.

Naya posted a ‘selfie’ of herself and Demi on set, and alongside it she coined the phrase ‘dantana’, bringing together the pair’s character names as they gear up audiences for the impending love affair.

It’s happening! Demi Lovato stormed the set of Glee on Thursday to take on the role of Naya Rivera’s character’s lover, marking a return to acting

According to the site, fans will get to see Demi in at least six episodes, beginning with the second part of the show’s Beatles’ tribute, airing October 3.

Demi has a close relationship with Glee’s Lea Michele already and recently came out in support of Lea’s boyfriend the late Cory Montieth who died of a drug overdose July 13.

The singer – who has admitted to using illegal substances herself – made an emotional plea for fans to not let the Glee star’s death from a heroin and alcohol overdose be in vain.

The X Factor judge told People: ‘All it takes is one moment of vulnerability to get slipped into your addiction.

‘It’s not a choice. Nobody chooses to use. He didn’t choose to die. It was the disease.

‘It can creep up on you at any moment. It only takes one moment of relapse to potentially die. It’s really scary, but I’m really hoping that from this, people are able to see this is a very, very, very dangerous disease.’
